I've made about 25 starters in my short brewing career using my homemade stirplate, and they've never looked like this. I am trying to revive an old Wyeast pack from this last summer that was part of a bad batch. I got the smack pack to swell after four or five days (maybe half swollen at best) and pitched it with a quart of wort Sunday afternoon. This morning the wort had changed color as it normally does but no foam in the vortex. Then I come home to the snow globe tonight. I was planning on adding another quart of wort but now I'm worried something isn't right. It's the ESB yeast, which I've not used before.
